Resumen:

To avoid shortcomings of the current models attempting to explain genesis of the Vrancea intermediate-depth earthquakes the alternative model of an unstable triple junction (VTJ) had been previously proposed mainly based on a speculative approach. The paper deals with results of the latest research, including high-resolution seismic tomography obtained through the joint inversion of seismic and gravity data, and numerical modelling of the mantle convection that brings new evidence to support VTJ as a valid alternative for Vrancea intermediate-depth seismicity geodynamic setting. Of a special interest proved to be the advanced numerical modelling run on a High Performance Computing Cluster own by Solid Earth Dynamics Department in the Institute of Geodynamics of the Romanian Academy that has demonstrated how a stable triple lithospheric contact may transform into an unstable triple junction under the influence of a thermal anomaly even in the absence of differences between the plates velocities. © 2017 European Association of Geoscientists and Engineers EAGE.
